bike was a NSU Fox, It is fitted with a one-piece tank-fairing, hammered out of aluminium.
Kawasaki H1
Not intended for the photo-gallery, but I thought it would be nice for you to see some of my own bikes, so I've attached scans of my Kawasaki 500
3-cilinders from 1969.
Kreidler racer
They are the bikes used in grand prix's by the Dutch "van Veen - racing team" in 1969. The riders were Aalt Toersen and Jan de Vries. The bikes are water-cooled, disk valve engines.
First Kreidler production racer
It's a 3-speed (hand change) 50cc racer. It has (forced) air cooling, and piston port induction with a Bing carburettor.
The bike is build / raced by a Kreidler spares specialist here in Holland, and is pretty fast!

Guazzoni "Matta" (1968); Italian 50cc production racer; 2 stroke with rotary valve inlet; bore x stroke 41x37.5; 4-speed gearbox (6-speed was optional available) of the "cassette-type" (quickly removable from the side); max power 8 hp@ 10.500 rpm (standard).
125 Condor
The 125 Condor, this was a development out of a 175cc Bridgestone based racer, and ws built by Henk van Kessel.
Motom 50
The Motom is an Italian 50cc vertical 4 stroke OHC, it is very different from the usual Motom "corsa". The chassis is most likely self build.
Motobi 125
The Motobi is a 125cc vertical push-rod 4 stroke, these bikes are called "power-eggs" here because of the shape of the engine.
Villa 250
The Villa is a 250cc 2 stroke single cilinder, probably based on a motocross bike. In the race, this bike was very fast, and could almost keep up with YamahaTD2's.
